SADIRON.

Specification of Letters Patent.

Patented July 265-, 1921.

Application filed March 30, 1920. Serial No. 369,910.

a citizen of the United States, and residing at New York, New Yorkcounty and New York State, have invented certain new and usefulImprovements in Sadirons, of which the following is a specification.

This invention relates to sad irons and more particularly to that classof irons which are heated from within and are provided with a watersupply that is converted into steam to moisten the goods which are beingpressed.

The object of the invention is to provide a sad iron with a gas supplypipe and an interior burner to heat the inside of the iron and a coil atthe inner end of a water supply pipe into which water is admitted by avalve at the outside of the iron and before the water reaches the end ofthe coil, it is converted into steam that circulates around the bottomof the iron and finally out of perforations thereat and on the fabricbeing pressed.

These and other objects and details of the invention are more fullydescribed in the following specification, set forth in the appendedclaims and illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of the improved sad iron.

Fig. 2 is a plan view of the same with the handle and guard plateremoved.

Fig. 3 is a sectional view through lines 3-3 of Fig. 2.

Fig. 4 is a plan View of the iron with the top removed.

Fig.5 is a cross sectional view.

The body of the iron consists of two sections 10 and 11,. held togetherby suitable screws 12, that also secure a guard plate 13, carrying ahandle 14, to the top of the iron and protects the hand of the operatorfrom any abnormal heat that may arise from the lI'OIl.

The part 10, constitutes the top of the iron and carries the nipples 15,and 16, to which are attached flexible tubes and the former nipple beingconnected with the burner, 17,

that extends below the top wall and into the section 10, and has anoutlet 18, covered with perforated sheet metal or wire mesh and openstoward the front of the iron so as to throw the flame toward that end,while the rear end of the iron has the door 19, around which suiiicientoxygen may pass for consumption by the flame.

This top section also carries a valve 20, that is the terminus of thenipple l6, and is inclosed in a casing 21, tonvhich is connected theupper end of the coil 22. The valve stem consists of the part 23, thatextends forward into the coupling 24, and is surrounded by the spring26, that abuts the head of the plunger 27, passing through the packingnut .28, and which is engaged at its outer end by -the lateral extension29, of a lever 30. The

outer end of the latter lever carries the vertical plunger 31, thatpasses upward through the plate 13, and has the knob 32, adjacent to thehandle 14, and adapted to be operated by the hand that holds the saidhandle to depresssame and throw the lever 30 to force the plunger 27inward and unseat the valve 20, thus permitting the water to enter thecoil 22, in quantities regulated by the plunger 31, and this amount isreadily determined by the operator to furnish only a certain quantity ofsteam and which is easily observable by him.

Within the bottom section 11, are two plates 33 and 34, the former beingmuch thicker than the latter to withstand the heat of the flame from theburner, and the plate 34 has ribs 35, on its upper side to provide spacebetween the plates for the circulation of the steam. The coil 22,delivers the steam to the under side of the plate 33, and it passes up apocket 36, in the said under side and downward through the opening 37,of a nipple 38, on the upper side of the plate 34, and the latter issupported above the bottom 39, by the ribs 40, thereon. After the steamthus circulates about the plates, it is free to pass out of theperforations 41, to moisten the goods being pressed. 0

The plate 33 is carried by the body section 10 and suspended by means ofa central screw 33 and the end of pipe 22 and forms a bottom to saidsection when the parts are assembled although the plate is located inthe lower section.

A gravity catch 42, holds the door 19, in its closed position and theribs of the bottom and the plate 34, may run on regular lines and bebroken at intervals to allow the steam to circulate laterally, while theperforations 41, may be arranged in lines or staggered to moisten thegoods more thoroughly over a larger area.

Even if the water in the coil is not en tirely vaporized when it reachesits outlet, it will be released on the upper face of plate .34, whichwill be sufficiently hot to convert it into steam, as suitable packingaround the edges of the plate will prevent leakage to the bottom 39, andthe water will eventually be evaporated. The operator will regulate hissupply of'water by the amount of steam arising from the goods as a largevolume will indicate to him that he is too liberal with the valve 20,and any water of condensation that may lodge above the plate 34, will bequickly evaporated by the heat of the burner if the water is shut offfor a short time and not allowed to pass into the outlet for steam.

It is obvious that the parts may be otherwise arranged or modifiedwithout departing from the essential features above 'described or fromthe scope of the appended claims.

What I claim as new is 1. In a sad iron, the combination of a hollowiron having perforations in its bottom wall, a dividing plate supportedfrom the top of the iron and having a pocket, a second plate with anipple adapted to enter the pocket of the first plate and trap waterabove the second plate, ribs adapted to form an open space on each sideof the second plate, a steam generating coil within the upper part ofthe iron and connected with the spac between the plates, a burneradjacent the coil, a valve admitting water to the steam coil, a handlefor the iron, and a lever controlling the valve and adjacent to thehandle.

2. In a sad iron, the combination of a hollow iron comprising aperforated bottom section and an upper section having a handle, a platein the bottom section and having a steam passage, ribs adapted toprovide spaces above and below said plate, a second plate above thefirst, a water trap between the two plates, a water pipe entering theupper section as a coil and terminating below the second plate, a fuelburner in the upper section, a normally closed valve in the water pipe,and a lever adjacent the handle to open the valve.

3. In a sad iron, the combination of a hollow iron comprising a topsection with inlets and a bottom section with outlets, a handle for thetop section, a fuel supply pipe and a water supply pipe entering the topsection, an open end coil at the terminus ofthe water pipe, a burner atthe end of the fuel pipe, a plate in the lower section and above the endof the coil adapted to receive the steam generated in the coil on itslower side, a second plate spaced between the first plate and the bottomof the iron and a trap to confine the water of condensation above thesecond plate.

4. In a sad iron, the combination of a hollow iron, a handle, a fuelsupply pipe .and burner, a water supply pipe, and coil adjacent theburner, means for circulating the steam generated in the coil about thebottom of the. iron, and out of outlets therein, a valve in the watersupply pipe and closed by a spring, a lever adapted to act upon the stemof the valve and open same, a plunger adjacent the handle and adapted tooperate the lever, plates in the bottom of the iron andhavingcirculating spaces between them, and a trap comprising a nipple and apocket to prevent the passage of water out of the outlets.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses, this 19th day of March, 1920.
